This document proposes an ontology modeling approach for measuring personality from social media activity. It involves collecting words from social media that reflect personality traits, constructing an ontology with personality traits as classes, facets as subclasses, and words as instances. An experiment analyzed Twitter data from 8 users to test the ontology model's ability to measure personalities based on OCEAN traits of Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. The results demonstrated the potential to integrate this ontology approach with machine learning to automatically classify personalities from social media data.

2. Changes in Behavior
▸ Post daily routines
▸ Share opinion, thoughts, and
information
▸ Communication

3. Activities on social media is stored as a digital trace
It provides us a new data resources
User also unconsciously reveal their personality through their writing and
linguistic text usage

4. Today’s Personality Measurement
▸ Via Interviews, Test, or
Questionnaire Suvey
▸ Most likely answer by what

17. Conclusion
▸ Measuring human personality based on social media
activity can be modelled using ontology approach.
▸ The components of ontology model are personality traits
as a class, facets of the personality as a subclass, and
the words that represent personality as an instance.

18. Benefits of Research
▸ Able to integrate with machine learning for automatic
classification.
▸ Bridge the gap between ontology and psychology research.
▸ Ontology model construction based on Bahasa Indonesia
for measuring human personality.
▸ Gives minimal effort to measure human personality.
▸ Gives cheaper and faster option to measure human
personality.

19. Suggestion
▸Enrich the model’s dictionary.
▸Giving weight to each word based on the phrase they are on.
